Tank is one of the over-classes a Co.R. pilot can choose for his robot.
The Tank over-class is all about armor and close distance combat.
Tank over-class provides two specialization: Gladiator and War Machine.

With the Gladiator specialization the Co.R. become a fully armored, brutal, melee warrior that masters the art of close combat.
The War Machine specialization upgrades the Co.R. capability to use ballistic weapons. Like the german panzer, the Co.R. will use its armor to survive to the enemy's shots giving the player the opportunity to fire the decisive bullet!
